I was confused. There should be a clearly visible video explaining it in 30 seconds.

Explaining why it exists, how it works and what it does; the problem, the solution.

The WHY is missing - WHY do you offer it? Why does it exist? - WHY should I care? - WHY should I be a part of what you do? - WHY do I need it?

Besides that I wish your project all the best. It looks very interesting!
